Using an eSIM for Mobile Internet in Malaysia
An eSIM is a digital SIM profile installed directly on your phone.
Instead of buying a physical SIM card after landing, you can install the eSIM before your trip while connected to WiFi.
After arriving in Malaysia, you select the eSIM as your mobile data line and enable data roaming on the eSIM if required.
This gives you mobile internet without removing your home SIM card.
You can start here:

However, buying a SIM card after arrival may involve:
- Finding a vendor
- Waiting in a queue
- Registration
- Physical SIM installation
- Changing your SIM setup
